Application tiled July 13, 1931. Serial No. 550,560.

The invention vrelates to safetyvlockers or Figure' 1 is a front elevation of a safety depositories of a type adapted to e installed in the tellers 'cages of banks, etc., to afford means for quickly and automatically locking the money in a chest, or the equivalent, in the event of a holdup, the primary object of theJ invention being to-providevimproved electrically operated means for controlling and operating the lockers. v

The lockers may be of any suitable construction, but preferably comprise a door, shelf, or the equivalent, upon which stacks of money may be placed during vbanking hours. Suitable means is provided for either dropping the money into the locker when an alarm isA given, or for quickly covering the money with a closure member.

The electrically operated means preferably comprises means for causing the closure member, shelf, or the like, to drop the money iut/o the depository, or to cause the closure member to move into a position wherein it encloses the money. The electrically operated means also preferably comprises means which `prevents access to the money for a predetermined period of time after the alarm has been given. The latter featu're is particularly advantageous as far as daylight holdups are concerned as itprevents any one from obtaining access to the money fora predetermined period of time aft-er an alarm has been given, and, therefore, an unauthorized person could not force a teller'to open the depository iinmediately but would have to wait for such a long period of time that in most cases no attempt would be made by an unauthorized person to gain access to the money.

ticularly adapted to be operatively connected to the improved alarmsystein shown and described in the co-pen'ding application of Albert L. Abbott, Serial-No. 453,060, filed May i 16, 1930. It will be noted,.however, that the invention may also be incorporated in electri- -cal signalingr systems which normally have supervisory currents flowing therein.

Other objects and advantages will become apparent as the following detailed description progresses, reference being had to the accompanying drawings, wherein:

Fig. 8 is a diagrammatic view of electrically operated apparatus which embodies another form of the invention, and

Fig. 9 is a diagrammatic view of electrically operated mechanism which embodies still another'form of the invention.

Referring for the present to Figs. `1 to 6, inclusive, wherein one form of the invention is illustrated, the reference character 10 d esignates, generally,'a safety depository which is particularly adapted to be employed in a tellers cage ofl a bank, or the equivalent, the safety depository being preferably mounted so that its top wall is flush with the top surface of the tellers desk which is shown at 11 in Fig. 1. In this instance, the safety detaken on line 5-5 of positoryf10 comprises a bottom wall 12, a Apparatus embodying the invention is parf manua-l operation of the bol'tworik.

The top wall 14 is provided with a relatively large opening which 1s provided with *dle 23 is provided upon the door 17 to permit a closure member or plate v26 which has depending flanges 27 at its ends. The closure plate 26 is mounted to swing around the axis of a spring-urged fluid-check mechanism 28 of the type which are generally referred to as door-checks. The mechanism 28 comprises the usual housing 29 from which a shaft 30 projects, thelongitudinal axis of the shaft 30'being the axis around which the closure plate 26 swings. The shaft 30 projects into a sleeve 31 rigidly secured in a bracket mem- Y ber 32 which is securedrto the bottom surface of the top wall 14. The sleeve 31 is adapted to prevent angular displacement of the shaft 30 around its longitudinal axis. The housing 29 is mounted on a block 34 which is secured to the bottom surface of a shelf 35 which is mounted between the flanges 27 and is constrained to move with the closure plate 26. Obviously, the housing 29 is also constrained to rotate around the longitudinal axis of the shaft 30 in unison with the closure plate 26 when the closure member 26 is moved from its open position to its closed position, or vice versa. p

In Fig. 2, the closure plate 26'is shown in its fully open position, and it will be noted that when the closure plate 26 is in this position the top surface of the shelf 35 lies flush with the top surfaceof the top wall 14 and substantially closes the opening 25 in the top wall 14.

. The shelf 35 provides means upon which the teller ma place stacks of money, the construction of t e improved safety depository being such that when an alarm is given, electrically operated apparatus hereinafter described causes the closure plate 26 and the shelf 35 to rotate in a counter-clockwise direction (Fig. 2) around the longitudinal axis of the shaft 30 so that the money is dropped into )the depository and the closure plate 26 moves into a position wherein it closes the opening 25 (see Fig. 3).

One of the flanges 27 is provided with'a notch 37. A spring-actuated latch device 38 secured to the bottom surface of the top wall 14 comprises a latch member 39 adapted to engage the notch 37 when the closure plate 2,6 is in its fully closed position. The latch device 38 comprises a handle 40 whereby one may retract the latch member 39 by reaching into the depository through the opening 1n the front wall thereof. When the closure plate 26 is in its closed position and the notch 37 is engaged by the latch member 39, access can not be had to the'contents of the depository unless the door 17 is opened.

A bolt 42 is slidably journaled in bracket members 43 secured to the bottom surface of the shelf 35. The back end of the bolt 42 projects into a dashpot 45. The front end of the bolt 42 is provided with bifurcations47 and 48. The bolt 42 is yieldingly urged to the left (Fig. 2) by a spring 49 and after it has been displaced to the right (Fig. 2), against the action of the spring 49, the dashpot 45 retards the bolt when it is retracted by the spring 49. The purpose of this construction will presently appear. When the closure` plate 26 is in its fully opened position, the bifurcation 48 is engaged by the inner end of a push rod 50, the outer end of which projects through the front wall 16. The push-rod 50 isl slidably journaled in bracket members 51 secured to the bottom surface of the top wall 14. A helical spring 52 wound around the push-rod 50 yieldingly urges the push-rod 50 to the left (Fig. 2) so that a collar 53 fixed to the push-rod normally abuts one of the brackets 51.

pushing against the outer end thereof. uchdisplacement of the push-rod 50 is accomplished by similar displacement of the bolt 42 against the action of the spring 49. This construction permits the teller to close the closure plate 26 at will as hereinafter more fully explained.

The bifurcation 47 co-operates with a magnetic lock 55. Inthis instance an Edwards No. 152 magnetic lock is shown. The magnetic lock 55 comprises a pivoted keeper 56, an armature 57 and electromagnets 58, the armature 57 being operatively connected to the keeper 57 which is normally urged by a spring 59 into a position wherein the bifurcation 47 may rest thereon when the closure member 26 is in its open position. Obviously, the keeper 56 is adapted to hold the closure plate 26 in its open position and to hold the shelf 35 in the position wherein its closes the opening 25 and serves as a tray for-holding money.

If the electromagnets are energized they The attract the armature 57 and retract the keepo er 56 so that the support is withdrawn for the bifurcation 47. The closure member 26 then swings into its closed osition under the action of the check mechanlsm 28. The same result may be obtained by pushing on the outer end of the push-rod 50 so that the bolt a magnetic lock 60 is associated with the bolt 21, the bolt 21 being provided with a hole 61 which may be engaged by a bolt 62 which forms part of the magnetic lock 60.

The-magnetic lock 60 also comprises electro-magnets 63 and a'n amature 64. A spring 65 wound around the bolt 62 yieldingly holds it in a position wherein it is reso that the boltwork of the door 17 can not, Qbe operated to unlock the door, the hole 61 being formed in the bolt 21 in a position vwhich insuresthat it will be alined with bolt I62 when the bolts 20 and 21 are in the positions wherein they lock the door 17 .in its closed position.

As best shown in Fig. 3, a stop member 67 projects from the back wall 13 and limits angular displacement of the closure plate 26 and the shelf 35 in a. counter-clockwise direction (Fig. 3).

As shown in Fig. 6, a block 7 of electrical insulation is mounted on the back surface of the front wall 16 and it carries electrical contact members 71 and 72 engageable with electrical contact members 73 and 7 4, respectively, which are mounted vin a block 75 of electrical insulation. The block 75 is mounted on the back surface of the door 17. The contact members 71, 72, 73 and 74 engage each other only when the door 17 is in its closed position and `when they engage each other they connect the electromagnets 63 to a source of electrical energy so that they may be energized when the circuit including them is closed.

The operation of the above described apparatus is substantially as follows: When the teller arrives at his desk he may open the door 17 by operating the combination lock 19 and manipulating the handle 23. The lever 40 may then be manipulated to retract the latch member 39 from the notch 37 to permit the closure plate 26 to, be swung into its open position s`o that the shelf 35 forms a continuation of the top Wall 14. The teller may then distribute stacks of money upon the shelf 35. After this has been done, the door 17 is preferably closed and locked by actuating the combination lock 19 or, if it is so desired, the combination lock may be left inits unlocked condition and the bolts 20 and 21 may be displaced to lock the door 17. When the bolts 2O and 21 are in their locked positions with the door 17 closed, the hole 61 is alined with the bolt 62. If at any time during the day the teller believes that an attempt is being made to holdup the bank. he may, if he has the opportunity, push against the outer end of the pushrod 50 so that the bifurcation 47 is retracted from the keeper 56, whereupon the shelf 35 will drop and permit the stacks of money to fall into the safety depository. At the same time, the'closure plate 26 will close the opening 25. After this happens, access can onlybe had to the money within the safety depository .by opening the door 17 and it is for this reason that the combination lock 19 is preferably kept in its locked condition.

If the signaling system, hereinafter described, is actuated any time during the day to give an alarm, the electromagnets 58 and 63 are energized. The electromagnets 63 then cause the bolt 62 to engage the hole 61 in the 70 bolt 21 so that the door 17 can not be opened until the electromagnets 63 are de-energized. When the electromagnets 58 are energized, the keeper 56 is withdrawn from beneath the bifurcation 47 and the closure plate 26 moves 7 5 into its closed position and the shelf 35 drops the money thereon into the safety depository. As hereinafter explained, the electromagnets 63 are preferably time-controlled and after they have been energized, they can not be deenergized for a predeterminedlength of time.

Therefore, if a hold up is in progress when they are energized, the robbers will, as a general rule, leave the bank before the electromagnets 63 are de-energiz'ed, as it will be 85 too dangerous for them to waituntilthe money within the safety depository is accessible. After the electromaguets 63 have been dcenergized, the door 17 may be opened so that the teller can rea-ch the lever 40 and retract -90 the latch member 39. After the latch member 39 has been retracted, the shelf 35 lnay again be brought into the position wherein it forms a continuation of the top wall 14.

In Fig. 7, a circuit is shown which embodies the invention and-is adapted to control and actuate the magnetic locks .55 and 60, which magnetic locks are included in the circuit. The circuit also comprises a relay 80, a timing-relay 81, a switch device 82 and 106 the magnetic locks 55 and 60 are enclosed"105 within the locker 10 and are not accessible when the door 17 is closed and the closure member 26 is in its closed position.

The apparatus disposed within the locker 10 is connected by conductors 85 and 86 -110 to an alarm system which is illustrated diagrammatically at 87. The alarm system 87 comprises a source of electrical energy, such as a battery 88, or the equivalent, and is provided with a switch 89, or the equivalent, 116

whereby the circuit may be opened when an alarm is to be given. The switch 89 may be a push-button switch, a switch operated by the feet, a switch device controlled by a photoelectric cell, as described in the above mentioned co-pending application, or any other suitable means which may be actuated manually or automatically to cause the alarm system to function.

The relay 80 comprises a winding 90 and 125 contacts 91 and 92 which are engageable by a contact member 93. When the relay 80 is energized, the contact member 93 engages the contact 91.

The timing-relay 81 comprises a `winding i?" y 55 tact 91.

95 and contacts 96 and 97 which are engageable by con-tact members 98 and 99, respectively. The contact 96 remains in engagement with the contact member 98 as long as 5 the relay 81 is de-energized and for a predetermined period of time thereafter, the timing-relayr81 being preferably provided with a dashpot device 96a which causes it to draw its armature up slowly when the circuit through-the winding 95 is closed. After the relay 81 has been energized for a predetermined period of time, the contact member98 is disengaged from the contact 96 and the contact member 99 engages the contact 97 The switch 82 comprises contacts 100 and 101 which may be engaged by a switch ele- A ment 103, the construction being such that When the closure member 26 is in its open position the switch element 103 engages the contact 100, but when the closure plate 26 moves into its closed position its final closing movement causes the switch element 103 to be disengaged from the contact 100 and brought into engagement with the contact y As shown, the conductor 86 is connected to one termin-al of the winding 90, the other terminal l of this winding being connected to the contact member 93, the negative terminal of the battery 83 and the Contact 97. The positive 4terminal ofthe battery 83 is connect ed to the switch element 103. The conductor 85 is connected to the contact 91 and the contact member 99. The contact 92 is connected to one terminal of the magnetic lock 55, the contact 98 and one terminal of the winding 95. The other terminal of this magnetic lock is connected to the contact 100. The

4 contact 96 is connected to the contact member 71, the contact member 72 being con nected to the contact 101 and to the other terminal of the winding 95. The contact members 73 and 74 are connected to the two ter- 45 mnals of the magneticlock 60.

The switch 89 is normally closed so that a supervisory current flows as follows From the battery 88 through the conductor 85, the A contact 91, the contact member 93, the Wind- 5 ing 90, the conductor 86 and thence through the switch 89 back -to the battery 88.' This current is of sufficient magnitude to hold the relay 80 energized so that the contact member 93 remains in engagement with the con- In the event the circuit through which the supervisory current flows is open or broken at any point, the relay 80 will be (le-energized. l Thus, an alarm signal may be given by opening the switch 89.

00 When the relay 90 is energized, the contact member 93 leaves the contact 91 and engages the contact 92. A current then flows as follows: From the positive terminal of the battery 83 through the switch element 103, the

contact 100, the electroni-aguets 58, the contact 92 and thence through the contact member 93 to the negative terminal of the battery 83. When the electromagnets are energized in this manner, they retract the keeper 56 so that the check mechanism 28 functions to bring the closure plate 26 into its closed position while the money stackedpn the shelf 35 falls into the locker. During the final closing movement of the closure plate 26, it disengages the switch element 103 from the contact 100 and brings it into engagement with the contact 101. The electromagnets 58 are cut out of the circuit in this manner to prevent a heavy drain upon the battery 83 as the electromagnets 58 have a low ohmic resistance.

When the switch element 103 engages the contact 101, a current flows as follows: From the positive. terminal of the battery 83,

through the switch ele-nient 103, the contacty 101, the contact members 71 and 74, the electromagnets 63, thecontact 96, the contact member 98, the contact 92, and thence through the contact member 93 to the negative terminal of the battery 83. The electromagnets 63 are then energized. and cause the bolt 62 to engage the hole 61 in the bolt 21 so that the door 17 will remain locked for a predetermined period of time, the length of which is determined by the relay 81.

A second circuit is closed when the ,switch clement 103 engages the contact 101. When this circuit is closed current Hows inl it as follows: From the positive terminal of the battery 83 through the switch element 103, the contact 101, the winding 95, the contact 92, and thence through the contact member 93 back to the negative terminal of the battery 83. The relay 81 then commences to pull up its armature. Then after a predetermined period of time has elapsed, the armature will be displaced suiliciently to disengage the coutact member 98 from the contact 96 and to bring the contact member 99 into engagement with the contact 97 The contact 97 is in parallel with the contact 91, and it will be noted that as long as the alarm circuit 87 remains open the relay 81 will remain energized and the contact member 99 will remain in engagement with the contact 97. When the alarm circuit is closed subsequently, the relay 90 is first energized by a current which flows as follorws: From the battery 88 through the conductor 85, through the contact member 99, the contact 97, the winding 90, the conductor 86, and thence through the switch 89 back to the battery 88. When the relay 80 is energized in thismanner, the contact member 93 leaves the contact 91 and engages.

the contact 92 so that the relay is energized by the current which flows as follows whenever the alarm circuit is in its normally closed condition: From the battery 88 through the conductor 85, the contact 91, the contact member 93, the winding 90, the conductor 86, and

thence through the switch 89 back4 to the battery 88.

The relay 81 may be adjusted so that it will take any predetermined time within a reasonable range to bring its armature into a position wherein it will disengage the contact member 98 from the contact 96 and bring the contact 98 into engagement with the contact member 97. As long as the contact 98 remains in engagement with the contact 96, the electromagnets remain energized and the door 17 can not be opened. However, as soon as the contact member 98 is disengaged from the contact 96, the electro-magnets 63 are deenergized and the door 17 may be opened so that the teller may manipulate the lever 4() to retract the latch member 39. The shelf 35 may be swung into its upper position and the stacks of money may be replaced thereon.

Another form of the invention is' illustrated in Fig. 8. The circuit shown in that figure includes the locks 55 and 60. The circuit also includes a relay 110, a slow-acting or timing relay 111, `a battery 112, a battery 113 and a switch device 114. All of these parts are enclosed within the locker 10 which is indicated by dot and dash lines. The circuit is operatively connected to an-alarm or signaling circuit deslgnated, generally, by the reference character 115, conductors 116 and 117 being provided for this purpose. The conductors 116 and 117 are connected to terminals 118 and 119, respectively, of the alarm or signaling circuit 115. The circuit 115 is preferably supervised by a relatively small current, the magnitude of which is controlled by a resistance 120. Connected across the resistance 120 is a shunt circuit 121 which includes a switch 122. The switch 122 may be located at any convenient point within the bank and may be actuated manually or automatically. The relatively small current, mentioned above, flows as follows: From one side of the circuit 115 through the resistance 120, the conductor 116, a winding 123 provided 'in the relay 110, and thencethrough the conductor 117 to the other side of the circuit 115. This current is insufficient to energize'the relay 110 but if the switch 122 is closed, the resistance 120 is shunted'out and the increased current lo'w will be sufficient to energize the relay 110. y

The relay 110 comprises the aboye mentioned winding 123 and a second winding 124. The relay 110 also comprises contacts 125,2126 and 127 which are engageable by contact members 128, 129 and 130, respectively. The contacts are engaged by the contact members when the relay is energized.

The slow-acting or timing relay 111 is preferably of the same construction as the relay 81, described above, and its primary function is the same. The vrelay ,111 comabove.

prises a winding 131, a contact 132, a contact member 133, and a dash-pot 111,

The switch device 114 comprises contacts 135 and 136 which are engageable by a switch element 137. The construction is such that when the closure plate 26 is in its open position, the switch element 137 engages the contact 135 but when the closure plate 26 is moved into its closed position, the final closing movement of the closure plate 26 is utilized to move the switch element 137 out of engagement with the contact 135 and into engagement with the contact 136.

Thelpositive side of the battery 112 is connected to one terminal of the magnetic lock 55, the other terminal of the magnetic lock 55 being connected to the contact 135. The positive terminal of the battery 112 is also connected to one terminal of the winding 131 and to one terminal of the winding 124. The

other terminal of the winding 131 is connected to the contact 136, the other terminal of the winding 124 being connected to the contact member 130.

The negative terminal of the battery 112 is connected to the-contact 132 and to the contact member 129.

The contact 125 is connected to the con`- i tact member 72 which engages the contact member 74 when the door 17 is in its closed position. The contact member 74 is connected to one terminal of the magnetic lock 60 which has its other terminal connected to the contact 73 which engages the Contact member 71 when the door 17 is in its closed position. The contact member 71 is connected to the positive terminal of the battery 113 which has its ne ative terminal connected to the contact mem er 128. The contact member 133 is connected to the contact 127 and engages the contact 132 when the relay 111 is de-energized.

The operation of the circuit shown in Fig. 8 is substantially as follows: If it is assumed that an attempt has been made to hold u the bank and the switch 122 vhas been close l it will be readily understood that the increased current flowing through the winding 122 will energize the relay 110,` as described The contacts 128, 129 and 130 will then engage the contacts 125, 126 and 127, respectively. A stick circuit will be closed for the relay 110, in which stick circuit current will flow as follows: From the positive terminafof the battery 112 through the wind-l in 124, the contact member 130, thev contact 12 the contact member 133, the contact 132,

and thence to the negative terminal of the battery 112. At substantially the same instant that the stick circuit is closed, a circuit will be closed for the magnetic lock, 55. Current will flow in the latter circuit as follows: From the positive terminal of the battery 112 through the electro-magnets 58, the contact 135, the contact member 137, the contact 126,

the contact member 129 and thence to the negative terminal of the battery 112. When the electro-magnets 58 are energized they will retract the keeper 56 so that the closure member 26 and the shelf 35 will move simultaneously into the positions wherein they are v shown in Fig. 3 so that the closure plate 26 contacts 74 and 72, the contact 125, and

thence through the Vcontact member 128 to the negative terminal of the battery 113. The electromagnets 63 are then energized and cause the bolt 62 to engage the hole 61 in the bolt 21 so that the door 17 is locked and can not be opened by manipulating the combination lock 19 and the handle 23.

As stated above, the final closing movement of the closure plate 26 causes the switch element 137 to leave the contact 135 and engage the contact 136. A current then flows as follows: From the positive terminal of the battery 112 through the winding 131, the contact 136, the switch element 137, the contact 126, the contact member 129, and thence to the negative terminal of the battery 112./ This energizes the relay 111, but as it is a as slow-acting relay and may be adjusted at willl it must be energized for a predetermined period of time before it causes its armature to disengage the contact member 133 from the contact 132. If this predetermined period of time isffifteen minutes, no access can be had to the interior of the locker 10 before the fifteen minutes have elapsed. Then if it is assumed that the switch 122 is open at the moment the contact member 133 leaves the oo ntact 132, the stick circuit for the relay 110 wall be openedy and the relay 110 will be deenergized so that the contacts 128, 129 and 130 will leave the contacts 125, 126 and 127, respectively. This opens the circuit for the magnetic lock 60, the circuit for the magnetic lock 55 having been opened when the switch element 137 is disengaged from the contact 135. Thecircuit is now in its closed condition and may be actuated again at the next alarm'. x

Fig. 9 illustrates a circuit which embodies another form of the invention, and may be utilized in connection with the locker 10. The circuit shown in Fig. 9 includes the magnetic locks 55 and 60 and also a quickacting relay 150, a timing or slow-acting relay 151, a switch device 152, a battery 153 and a battery 154. All of these parts are enclosed within the locker 10, which is indicated by dot and dash lines in Fig. 9. The

Aclosure plate 26 is in its open position.

apparatus enclosed within the locker 10 is connected to an alarm or signal circuit which is designated generally by the reference character 156. Conductors 157 and 158 connect the lelectrical apparatus within the locker 10 to the alarm circuit 156. 'lhe alarm circuit 156 may comprise any suitable apparatus such, -for instance, as the alarm or signal circuit shown in the co-pendmg application vmentioned above. In Fig. 9, the alarm circuit 156 is illustrated diagrammatically and Ais p'rovided with a source of electrical energy which, inthis instance, comprises a battery 158. The positive terminall of the battery 158 is connected to a switch 159 which may represent any of the means provided in the co-pending application for sending an electrical current through the system. In this instance, it may be assumed to be a pushbutton which is accessible 'to the teller or to soml other properly authorized person in the ban Under normal conditions no current flows in the conductors 157 and '158, but if the switch 159 is closed, inthe'event of a hold- .ing relays 81 and 111, described above, and

its primary function is the same. The relay 151 comprises a winding 166, a contact 167, a contact member 168, and a dash-pot 151. The contact member 168 normally engaging the contact 167, but after the relay has been energized for a predetermined period of time its armature will disengage the contact member 168 from .the contact 167.

VThe switch device 152 comprises a contact 170 and a switch element 171. The switch element 171 engages the contact 17 Owheibr the ()\V ever, when the closure plate 26 moves into its closed position it disengages the switch element 171 from the contact 170 during its final closing movement.

The electro-magnets 58 of the magnetic lockV 55 are connected to the conductors 157- and 158, the contact 170 and the contact member 171 being arranged in series with the electromagnets 58. The conductor 157 is connected to one terminal of the `winding 166 and to one terminal of the winding 160, the conductor 157 being also connected to the positive termina-i of the battery 154. The other terminal of the winding 166 is connected to the contact member 163, the other terminal of the winding 1,1'60 being connected to the contact member 168. The contact 167 is connected to the conductor 158. The negative terminal of the battery 154 is connected to the contact 161. The positive terminal of the battery 153 is connected to one terminal of the magnetic lock4 60 which has its other terminal connected to the contact 162. Thel negative terminal of the battery 153 is connected to the contact member 164.

The operation of the apparatus shown in Fig. 9 is as follows: If it is assumed that an attempt has been made to hold up they bank and the switch V159Y has'been closed, the following sequence of operations will o ccur. Current will flow as follows: From the positive terminal of the battery 158 through the switch 159, the conductor 157, the electromagnets 58, the switch element 171, the contact 170 and thence through the conductor 158 to the negative terminal of the battery 156. Vhen the electromagnets are energized in this manner, they will retract the keeper 56 so that the closure plate 26 will move toward its closed position.- During the final closing movement of the closure plate it will disengage the switch element 171 from vthe contact 170 to prevent any further drain llpon the battery 156 by the electromagnets The relay 151 is energized simultaneously with the magnetic lock 55 by a current whichV flows as follows: From the positive terminal of the battery 158 through the switch 159,

the conductor 157, the winding 166, yand thence through the conductor 158 to the negative terminal of the battery 156. `At the same time, the relay 150 is energized by current which flows in parallel with the current thence through the Contact 167 to the conductor 158.

The quick-acting relay 150 closes the circuits controlled by the contacts 161 and 162 immediately. The electromagnets 63 of the magnetic lock are then energized by a current which flows as follows: From the positive terminal of the battery 153 through the windings of the electro-magnets 63,'the contact 162, the Contact member 164 and then to the negative terminal of the battery 153. When the electro-magnets63 are energized in this manner they cause the bolt 62 to engage the hole 61 in the bolt 21 so that the -locker can not be opened until the timing relay 151 has disengaged t-he contact 167 from the contact memberV 168. Y

The engagement of the contact 161 by the contact member 163 closes a circuit in which currentfiows as follows: From the positive terminal of the battery 154 through the wind- 4ing l166, the contact member 163, 'the contact 161 and then to the negative' terminal of the battery 154. Another current flows as follows: From the positive terminal of the battery 154 through the Winding 160, the contact member 168, the Contact 167, the contact member 163, and thence through the contact 161 to the negative'terminal of the battery 154.

The current flowing from the battery 154 and through the winding 166 is insuiicient to cause the relay 151 to displace its armature so that it will disengage the contact member 168 from the contact 167. Therefore, if the flow of current through the conductors 157 and 158 from' the battery 156 is interrupted for any reason, the locker 10 can not be opened until the flow of currentthrough the conductors 157 and 158 and the winding 166 is re-established. Assuming that the circuit which includes the battery 156 and the conductors 157 and 158 is closed and that the battery 154 is also supplying current to the winding 166the relay 151 will cause its armature to disengage the contact member 168 from the Contact 167 after a predetermined period oftime has elapsed.A l/Vhen the contact member 168 leaves thecontact 167, the relay 150 is de-energized and the contacts 161 4.and 162 are disengaged from the contact meinbers 163 and 164, respectively the circuits energized by the batteries 154 and 153 will be opened and the electiomagnets 63 will be energized so that the bolt 62 will be withdrawn from engagement with the bolt 21. Then, if

the circuit l156 is opened, the relay 151 will be de-energized and the apparatus will be restored to its normal condition so that it may be actuated whenthe next alarm signal is given. v

s stated above, the magnitude of the current which Hows through the winding 166 from the battery 154 is 'not sufficiently large to cause the armature of the relay'151 to disengage the contact -member 168 from the contact 167. However, this current will hold the armature in any position it happens to be in when the flow of current through the conductors 157 and 158is interrupted.

The current which Hows through the winding 160 from the battery 154 will hold the relay 150 energized even though the flow of current through the conductors 157 and 158 is interrupted and, therefore. if these wires are cut, or if the switch 1 59 is opened the relay 150 will remain energized and keep the electromagnets 63 energized, and while these electromagnets 63 are energized, the locker can not be opened.

The magnetic lock 60 functions as a lock when it holds the closure plate 26 and the shelf 35 in the positions wherein they are shown in Fig. 2, Vbut it also functions as a trip-device and may be described as a magnetically operated trip-device.
